Opening an I01 File
The I01 file type is primarily associated with Invoice Manager.
What is an I01 file?
I01 files mostly belong to Invoice Manager. An I01 file type has two common uses.
- Invoice File: It acts as an internal format for storing invoice data. The file holds billing records and transaction details. Only the designated invoice application can display its contents correctly.
- Forensic Image Segment: Alternatively, it can be a part of a split forensic disk image. In this case, the file represents one segment of a larger image used in digital forensic investigations. Forensic tools combine it with other segments to view the complete image.

How to open an I01 file
You need a suitable software like Invoice Manager to open an I01 file. Without proper software you will receive a Windows message "How do you want to open this file?" or "Windows cannot open this file" or a similar Mac/iPhone/Android alert. If you cannot open your I01 file correctly, try to right-click or long-press the file. Then click "Open with" and choose an application. You can also display a I01 file directly in the browser:. Just drag the file onto this browser window and drop it.

Programs that open and convert I01 files:
- Invoice Manager
See the previous paragraphs to learn more about the main application. I01 files are often referred to as Invoice Manager data files because this type of file is primarily created or used by this software.
- Forensic Software (e.g., EnCase, FTK)The .I01 file extension represents a segment of a split forensic disk image. Forensic disk images are often split into smaller segments for easier storage and transfer. The .I01 file specifically indicates the first segment of a split image. Other segments would be sequentially numbered (e.g., .I02, .I03, etc.). These files are crucial for forensic analysis, allowing investigators to examine the contents of a drive without altering the original evidence. The internal structure of these files depends on the specific forensic software used to create them. Reassembling these segments is necessary to access the complete image for analysis. This file format is classified as Disk Image.
I01 format details:
Why is it important to know the file format? This is the only way to find out which program to use to open the file. Often, the file format can be deduced from the file extension or the initial bytes (called the signature). If the file extension or signature does not match the file format, errors will occur when opening or editing the file. Knowledge is power - this also applies when dealing with unknown or faulty files. Our analysis of the I01 files produces the following result:
The I01 file extension is not common and includes various formats for various programs. But the following two file formats are common:
- 35% of all I01 files use the same file format, which can be identified by the letters "08 09 FE 02" at the beginning. These are binary files, so they do not contain words or text. The average file size is 130 KB with most files being between 46 KB and 610 KB in size. The file type was developed 10 years ago and is still in use today.
- 15% of all I01 files use the same file format, which can be identified by the letters "ELZ" at the beginning. The content consists of illegible binary data, which can only be read and interpreted by the associated programs. The files are 10 KB to 10 KB in size, with a median of 10 KB. Certain words are almost always found in the files, such as ELZ#.
All other I01 files (50%) have different formats, frequently e.g. IsZ. These files are often connected to batocera, plus or zent. If you want to find out which format your I01 file belongs to, just click on the button "Choose your .i01 file to analyze".
